Question

PARTA

☺
It takes Mrs. Miklos 5 minutes to grade 7 quizzes. At this rate, how many quizzes can she grade in 15 minutes?

Answer 1

21 quizzes

Explanation:

Divide 15 by 5 to know how many 5 minutes are in 15 minutes.

`15 / 5 = 3`

5 minutes are spent for 7 quizzes.

5 × 3 minutes are spent for 7 × 3 quizzes.

`7 * 3 = 21`

Mrs. Miklos can grade 21 quizzes in 15 minutes.
